Falk Gearbox Repair
Falk parallel-shaft, right-angle and worm gear reducers rebuilt in our Rialto, CA shop — for conveyors, crushers, mixers and heavy industrial drives nationwide.
Repair experience with Falk gearboxes
American Gearbox Repair repairs and rebuilds Falk gearboxes used across mining, cement, aggregates, material handling and general industry. Our repair experience covers Falk parallel-shaft reducers, right-angle and worm gear units, and the heavy-duty enclosed drives commonly found on conveyors, crushers, bucket elevators, mixers and kilns.
Please note: we are not an authorized dealer or authorized service center for Falk. We repair Falk equipment based on our repair experience, using inspection, measurement and rebuilding practices developed over years of working on industrial gearboxes.
Every Falk unit that arrives at our shop is fully disassembled, cleaned and inspected before we quote the repair, so you know exactly what failed and what it will take to put the unit back into reliable service.
Common Falk gearbox problems we fix
- Gear tooth pitting and spalling — from shock loads on crushers and conveyors, or from contaminated oil
- Bearing failure — worn input, intermediate and output bearings causing noise, heat and vibration
- Seal and oil leaks — hardened input and output shaft seals, worn seal journals and damaged gaskets
- Backstop and brake problems — slipping or failed backstops on inclined conveyors
- Housing wear and fretting — bearing bore wear, cracked feet and damaged mounting surfaces
- Cooling and lubrication issues — failed shaft fans, clogged breathers and oil starvation damage
How we rebuild your Falk gearbox
1. Inspection and failure analysis
We tear the unit down completely, measure gear teeth, shafts, bearing bores and housing fits, and check oil condition and wear patterns to find the root cause — not just the broken part.
2. Repair or replace
Worn gears can often be re-cut or manufactured new in our shop. Shafts are reground or replaced, bearing bores are repaired, and housings are checked for cracks and flatness.
3. Reassembly and testing
The unit is reassembled with new bearings, seals and gaskets, set to the correct backlash and bearing preload, filled with the right lubricant, and run-tested for noise, temperature and leaks before it leaves.
Replacement components
We source or manufacture bearings, seals, gaskets, gears, pinions, shafts, backstops, fans and breathers for Falk reducers. When a part is obsolete or has a long lead time, our gear manufacturing capability often lets us make it instead of waiting.
